The present application is a 371 of PCT/AU02/01165 filed on Aug. 29, 2002, which is a continuation of U.S. application Ser. No. 09/942,602 filed Aug. 31, 2001.
1. Field of the Invention
The present invention relates to an electronic book or “e-book” being a device that presents text and/or graphics, for example the text of a book or magazine and associated pictures, upon an electronic screen. Such devices typically comprise a display screen, for example an LCD screen under control of a programmed microprocessor. The microprocessor reads data from a data storage medium such as a Micro-CD-ROM or memory card such as a PCMIA card and converts the data into text and/or graphics that are displayed on the LCD screen.
2. Description of Related Art
One commercially available electronic book is the REB1100 available from RCA. That device has a monochrome LCD touch screen and a built in 33.6 kbps v.34 capable modem that allows digital book data to be downloaded from a remote database into an onboard 8 MB memory.
In U.S. Pat. No. 6,229,502 there is described an electronic book which is configured to read digital book data from a ROM such as a PCMIA card.
In U.S. Pat. No. 6,037,954 to McMahon there is described an electronic book which includes a Micro-CD-ROM drive for reading digital book data encoded onto a Micro-CD-ROM.
One problem with these devices is that they rely on data storage or distribution systems which are relatively expensive and complex to implement.
It is an object of the present invention to provide an electronic text and/or graphics presentation device that is capable of reading book data encoded on a low cost, high capacity medium that may be conveniently carried.
According to the present invention there is provided an electronic text and/or graphics presentation device including:
a user input control means;
processing means coupled to the scanning means and responsive to the user input control means and operatively programmed to generate a data signal corresponding to the text and/or graphics; and
a display means controlled by the processing means and arranged to display the text and/or graphics in response to the processing means.
In order that the device be compact it preferably includes a foldable housing comprising first and second housing portions pivotal relative to each other.
According to the preferred embodiment the first and second housing portions are each pivotally connected to a common spine.
Batteries for powering the unit may be conveniently located in a battery compartment formed in the spine.
It is desirable that the pattern be formed on a card and said device includes a roller mechanism arranged to retract the card into said device.
In the preferred embodiment the roller mechanism is incorporated into the first housing portion.
In order for a user of the device to readily determine if the device is loaded with a card the first portion may include a window for observing cards retracted into the first portion.
Preferably the device includes a card storage magazine which may be located in the second portion.
The display means may comprise a flexible LCD screen that is located across inner surfaces of the first and second housing portions.
In order to reduce power consumption it is advantageous that the flexible LCD screen be of a bi-stable type.
Preferably the housing includes a recess, for example formed in the spine, for receiving a loop of the LCD screen upon pivoting the first and second housing portions to a closed position in order that creasing of the LCD screen is avoided.
In order to allow for a compact construction it is preferred that first and second printed circuit boards are located in the first and second housing portions respectively.
The flexible LCD screen may include conductive traces coupling the first and second printed circuit boards to each other.
In the preferred embodiment the user input control means comprises a joystick assembly.
According to a further aspect of the present invention there is provided an electronic text and/or graphics presentation device including:
a scan head arranged to scan a pattern corresponding to text and/or graphics;
a processor coupled to the scanner and configured to generate data corresponding to the text and/or graphics;
a display screen responsive to the processor and arranged to display the text and/or graphics.
According to a final aspect of the present invention, there is provided a method for distributing text and/or graphics comprising the steps of:
encoding the text and/or graphics as a printed pattern on a plurality of cards;
distributing the cards to a plurality of users;
providing each of the users with an electronic text presentation device including means arranged to scan one of said cards and convert said pattern into readable text.
The drawings illustrate an electronic book that is configured to read data encoded as a pattern printed on a sheet of card.
With reference to
At the top of the outside of front door 6 there is located an eject button 12. Upon operation of the eject button, card 18 is ejected from the e-book by the internal roller mechanism.
At the base of spine 16 there is located a battery cover 4 that covers a battery compartment for accommodating two AAA size batteries that power the e-book.
The outside of rear door 8 is visible in
The LCD screen operatively displays the text of the book encoded on card 24. A user of the e-book is able to control which page of text is presented by means of joystick 26.
The internal arrangement of the e-book may be comprehended by referring to
Adjacent scan head 30 there is located a motor 32 which drives roller 34 via reduction gearing. A switch 36 is provided to detect depression of eject button 12.
Power for the electric motor and various circuit modules is conveyed from a battery compartment in the spine of the e-book to PCB 28 by means of cable 29.
A block diagram of various electronic components of the e-book is shown in
Processing module 44 includes a central processing unit 46, which communicates with BIOS memory chip 48 and RAM 50 in the conventional manner. The CPU operates according to a program stored in program memory chip 52. The processing module receives data and control signals from eject sensor 36, joystick 26 and scanner 30. In a further, more complex implementation, LCD screen 24 may be touch sensitive in which case the processing module would also be responsive to command signals generated by a user touching the LCD screen.
In operation a book data card is inserted through card slot 24. In response card insertion sensor 48 generates a signal alerting processing module 44 to activate electric motor 32 thereby causing roller 34 to draw the card into internal cartridge 38. As the card is drawn in scan head 30 converts a pattern on the card into corresponding data signals which are decoded by CPU 46 according to an algorithm implemented in the software stored in program memory chip 52. The resulting decoded text file is stored in RAM 50.
The decoded signals are displayed as readable text on LCD 24 under control of display controller 44. Of course, as referred to previously, in magazines and some books, such as childrens' books, technical volumes and manuals, illustrations or graphics may feature prominently. Accordingly, the software stored in program memory chip 52 may also include instructions to decode figures encoded on the book data card.
The processing module 44 is responsive to signals generated by joystick 26 and is programmed to allow a user to move forward or backwards through the displayed text. In particular, processing module 44 retrieves different data segments from RAM 50 in response to movement of the joystick.
Several systems for encoding the data cards are appropriate and have been described in the prior art. For example, in U.S. Pat. No. 6,176,427 there is described a method for coding digital data, such as a text file, into a pattern printable on an A4 or Letter size piece of paper. In the system that is described it is possible to encode slightly more than 1 MB of data on to one side of a printed letter size page of paper using a high resolution printer and a 600 dpi scanner. In the presently described preferred embodiment the scanner head 30 is implemented by means of the scan head technology described in the previously incorporated U.S. patent application Ser. No. 09/113,053 Such a scanner has an output resolution of 4800 dpi.
It is further envisaged that the data card be produced using the very high resolution print heads described in the previously referred to U.S. patent application Ser. No. 09/113,053. Accordingly the amount of data that may be stored on a data card of dimensions 8.5 cm×5 cm (3.5″×2″) is approximately 1 Mb. Encoding of the text on to the data card may be performed as described in U.S. patent application Ser. No. 09/112,781 which is hereby incorporated by reference in its entirety.
Accordingly an entire novel may be stored on a single credit card sized plastic card by means of a pattern formed as an array of 16 million printed ink dots. The manufacturing cost per card is less than 1 cent, or about one fiftieth the cost of manufacturing a floppy disk. While it is envisaged that the card be made of plastic it would also be possible to use other substrates such as paper.
While it is primarily envisaged that the data stored on the data card will correspond to the text of a book or magazine, it is also possible to encode an executable program file. Accordingly updates to the software program stored in program memory 43 may be conveniently distributed in the form of encoded data cards.
The mechanical arrangement of the e-book will now be described further with reference to
